CF-18V: 12 VDC Variable Speed, Timer Operated

12 VDC, Variable Speed, Manual/Timer Controlled Air Sampler

The CF-18V field unit operates on a single 12 volt automotive battery (not included). The two stage centrifugal fan pump motor is speed controlled by a rheostat which allows an operator to set a desired volumetric flow rate. An In-Line venturi allows for instantaneous flow measurement directly from an individually calibrated Magnehelic®. Continuous or 0-30 minute grab samples can be taken on a variety of "CF-Type" combination or paper only filter holders. Browse the Air Sampling Accessories section for optional 12/24 Volt DC Portable Power Source (P/N: PPS-12/24-VDC).
